Another object of this invention is to provide in a lock of thecharacter described wherein a pair of vertical bolts are moved outwardlyaway from each other into engagement with a keeper, simultaneously withthe projection of a horizontal bolt, invertible actuating mechanism forconverting the lock for use with vertical bolts adapted to be movedinwardly toward each other upon projection of said horizontal bolt. i

A further object of this invention is to provide a neat, compact andstrong lock of the character described which shall comprise fewandisimple parts, which shall be of economical construction, smooth andpositive in operation, which shall be easy to assemble and disassembleand which shall yet be practical and efficient to a high degree.

Other objects of this'invention will in part bev obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts which will beexemplified in the construction hereinafter described, and of which thescope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of the variouspossible illustrative embodiments of this invention,

Referring now in detail tothe drawings, 10 designates a portion of adoor on which is mounted, adjacent the vertical edge 11 thereof, a lock12 here shown as carrying a plurality of bolts i930, serai No. 487,969

(o1. vii- 74) adapted to cooperate in the manner hereinafter describedwith a strike or keeper 14 attached to the door jamb 15. The lock 12comprises a casing 12a having a front Wall 18, top and bottom walls 19and 20, an end wall 21 remote from the 60 i edge 11 of the door, anda'second end wall 22 26 adjacent said rear edge 25 thereof, for seating7.0`

a cover plate 27. Said cover plate may be secured to said casing in anysuitable manner, as for instance rby meansv of screws -extending throughthreaded openings 30 in bosses 31 integrally formed with the topandbottom walls 19 75 and 20 of said casing 12a.. `The casing 12afurthermore may be formed with symmetrical aligned wall portions 32extending outwardly from said top and bottom Walls 19 and 20 anddisposed parallel to the end wall 22. Extending outwardly from said topand bottom walls 19 and 20 are walls 33 parallel to the front wall 18and joining the walls 32 and 22. It will be noted that the walls 32, 33and 22 form with the cover plate 27 a pair of tubular openings 35 at thetop and bottom of the casing adjacent the front wall 22 andcommunicating with the interior of the casing.

For the purpose hereinafter appearing, the front wall 18 is formed witha pair of integral parallel ledges or guides 36, 37. The boss 31extending from 'the rbottom wall 20 may likewise be provided with a flatsurface V39 parallel to said steps 36, 37. Slidably mounted within thecasing 12a, and guided by and between the parallel step 37 and saidsurface 39, is a member 40 having a plate portion 41 parallel to saidfront wall 18. Said member 40 is provided with an extension 41a restingon and guided between the steps 36, 37. Extending from said plate 41 atright angles thereto is an integral plate portion or wall 42 disposedparallel to the end wall 22 of the casing.

It will be noted that said member 40 may be reciprocated within thecasing 12d.- The front wall 18 of the casing may be provided adjacentthe top and bottom walls 19 and 20 thereof with parallel ledges 40a and40h, supporting and serving as guides for the end portions 42a and -42bof said wall 42. i i

Means is provided for reciprocating saidV member 40 within the casing.To this end, the front wall 18 of the casing is formed with an integralboss 50 having a bore rotatably receiving a nger knob 51 projecting intothe casing. Fixed to the inner end of the knob is an arm 52 having a pin52a at the outer end thereof pivoted to one end of a link member 53,said link being pivotally attached at the other end thereof to pin 54iixed to said plate 41.

It will now be seen that upon rotating the knob 51, the arm 52 isrotated therewith for moving the link 53 and causing sliding movement ofthe member 40. Any suitable key control mechanism 56 may be mounted on acover plate 27 and provided with an arm 57 substantially contacting thenism 56, the arm 57 is rotated and the lug 58l actuates the link 53 fortranslating said member 40.

A coil spring 59 may be mounted on a rearward extension of said pin 54,and provided with end extensions 60 engaging portion 53a. of the link 53and the plate portion 42 for normally urging said member 40 toward theend of its stroke in either direction. The wall 42 is provided with apair of spaced symmetrical openings 61 and the front wall 22 of thecasing is provided with a pair of openings 62 aligned with said openings61, for the purpose hereinafter appearing.

Mounted on said wall 42 are a pair of horizontal similar bolts'63 and 64having reduced portions 63a and 64a extending thru saidopenings 61, theend portions of said bolts being slidably disposed within the openings62 in end wall 22. Extending rearwardly from and iixed to plate portion41 of said member 40 are pins 65 and 66, said pins extending thru saidportionsy 63a and 64a of said bolts 63, 64, respectively, for xin saidbolts to said member 46.

It will thus be seen that -thebolts 63, 64are xed to member 40 by meansof pins 65, 66 re' spectively, and that said bolts may be projected fromthe casing or retracted into the casing upon actuation of the fingerknob 51 or the key actuating mechanism 56. As illustrated in Fig. 1 ofthe drawings, the lock is provided with a pair of vertical bolts 70, 71adapted to be moved outwardly away from each other simultaneously withthe projection of the horizontal bolts 63, 64. Said bolts 70 andy 7l aresymmetrically disposed with respect to one another and are provided withportions 72 and 73 respectively slidably extending within thetubular'openings 35 of the casing 120;. Extending inwardly from saidportions 72, 73 are iiat plate portions 74, 75 having pins 74m and 75afixed thereto adjacent the inner ends thereof and projecting rearwardlytoward said cover plate 27. Mounted within the casing adjacent the'coverplate 27 and disposed between said cover plate and the wall 42 of member40 are a pair of symmetrically disposed plate members and 8l to bedescribed in detail hereinafter.` Said members 80 and 81 are providedadjacent one end thereof, with substantially ovalshaped slots 82 and 83respectively, pivotally and slidably receiving said pins 74a and 75a.Said members 80, 81 are furthermore pivoted adjacent the oppositeend tothe cover plate 27 by means of pins 84, 85 iixed to the inner side ofsaid cover plate. Said members 80 and 81 are also provided withelongated inclined slots 87 and88 respectively,

slidably receiving the upper ends of the pins 65, 66. As shown in Fig.1, the slots 87, 88 are inclined inwardly toward each other and towardend wall 22 and are, further symmetrically disposed with respect to thelongitudinal mid-section of the casing. It will thus be seen that uponactuation of the knob 51 for moving the member 40 to the right, as seenin Fig. 1, the bolts 63, 65 will be projected from-the casing and thepins 65, 66 will move within the slots 87, 88 for causing pivotalmovement of the members 80, 81 about pins 84, 85, away from one another.Such movement of said members 80, 81 will cause outward sliding'movement of the bolts 70, 71 away from each other, due to the pin andslot connections 74a, 82 and 75a, 83, into engagement with keeper 14.Said members 80, 81 thus have cammed connections with the bolts.Obviously, actuation of the knob 51 in the opposite direction will causemember 40 to slide to the left for retracting the bolts 63, 65 andcausing pivotal movement of the members 80, 81 about the pins 84, 85inwardly toward each other. This action will move the bolts 70, 7linwardly toward one another for disengaging the same from the keeper 14.Said bolts 70, 7l are provided with portions 90 and 91 respectively,parallel to each other and adapted to overlap the door jamb. Said boltsare furthermore provided with outwardly extending aligned portions 92and 93 adapted to engage within suitable openings in said keeper 14.Said keeper obviously is provided with suitable openings for receivingthe forward ends of the horizontal bolts 63, 64 whereby both horizontaland vertical bolts may be simultaneously moved into engagement with orout of `engagement from said keeper.

In Fig. 4, the bolts 100 and 101 are U-shaped and are providedzwithportions 102 and 103 extending inwardly toward each other and adaptedto'engage Within openings 104 and 105 respectively, of a keeper 106. Thepivoted members 80 and 81 however, are inverted from the position showninFig. l so that the inclined slots 87 and 88 will diverge away from thelongitudinal midsection of the casing and toward the end wall 22 insteadof toward said mid-section and toward said end wall, as rshown inFig. 1. Said members 80 and 81 are pivoted to the cover plate 27 bymeans of said pins 84, 85 and are also provided with slots 82 and 83slidably receiving therethrough, pins 107 and 108 extending rearwardlyfrom inner portions of the bolts 100 and 101.

It will now be understood that upon projection of the bolts 63, 64 themembers 80 and 81 will be pivotally moved toward each other due to theaction of the pins 65 and 66 within said slots 87, 88. This movement ofthe members 80 and 81 will cause the U-shaped bolts 100 and 101 to moveinwardly toward each other into engagement with the strike 106, thehorizontal bolts 63 and 64 simultaneously moving into engagement withinopenings 109 and 110 in said keeper. Actuation of the finger knob in theopposite direction will cause retraction of the horizontal bolts 63, 64and movement of the pivoted members 80, 81 away from each otherspreading the bolts 100 and 101 and disengaging the portions 102 and 103thereof from the strike 106.' Y

It will thus be seen that for adapting the lock shown in Fig. 1 for usewith bolts to be moved inwardly toward each other upon projection of thehorizontal bolts, the pivoted members 80 and 81 need merely be invertedin the manner illustrated and described, and the U-shaped bolts 100 and101 substituted for the bolts 70 and 71.

It will thus be seen that there is'provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodimentset forth, it isto be understood that all matter herein set forth or shown in theaccompanying drawingsis to be interpreted as illustrative and not in alimiting sense.
